The Magnus effect is not responsible for the movement seen in conventional swing bowling, [30]: Fig. 4.19 in which the pressure gradient is not caused by the ball's spin, but rather by its raised seam, and the asymmetric roughness or smoothness of its two halves; however, the Magnus effect may be responsible for so-called "Malinga Swing", [31 ...
A serve (or, more formally, a service) in tennis is a shot to begin the point. The most common serve is used is an overhead serve.It is initiated by tossing the ball into the air over the server's head and hitting it when the arm is fully stretched out (usually near the apex of its trajectory) into the diagonally opposite service box without touching the net.
